          12. COOLING SYSTEM

 SERVICE INFORMATION

 GENERAL INSTRUCTIONS
 · The water pump must be serviced after removing the engine. Other cooling system service can
   be done with the engine installed in the frame.
 · The engine must be cool before servicing the cooling system.
   When the coolant temperature is over 100 , never remove the radiator cap to release the
   pressure because the boiling coolant may cause danger.
 · Avoid spilling coolant on painted surfaces because the coolant will corrode the painted surfaces.
   Wash off any spilled coolant with fresh water as soon as possible.
 · After servicing the system, check for leaks with a cooling system tester.
